Oxidation-specific epitopes in atherosclerosis

During the development of atherosclerotic lesions, low-density lipoproteins (LDL) deposit in the wall of large and medium-sized arteries, where they become oxidized and are taken up by infiltrating macrophages resulting in the formation of foam cells. This process is also characterized by inflammatory reactions and the accumulation of oxidized LDL as well as apoptotic cells in the vascular wall. Notably, both oxidized LDL and apoptotic cells carry the same oxidation-specific epitopes (OSE), which represent danger-associated molecular patterns that are recognized by the innate immune system.

We hypothesize that OSE are key drivers of the inflammatory response in atherosclerosis. Therefore we are investigating how macrophages sense OSE and study the functional consequences of this in the development of atherosclerotic lesions. Key areas include the identification of the receptors and molecular pathways that are mediating these effects, and the development of strategies to inhibit these specific inflammatory responses.

Natural antibodies and the complement system in atherosclerosis

Natural antibodies are pre-existing germline-encoded antibodies that are primarily of the IgM class and secreted by a specialized subset of B1 cells. They play an important role in the first line defense against microbial infections and provide important “house keeping” functions by recognizing damaged self antigens. Natural IgM protect mice from atherosclerotic lesion formation, and data from our group demonstrated that a large part of natural IgM antibodies has specificity for OSE. Ongoing projects focus on the identification of the mechanism by which natural IgM mediate atheroprotection and whether the recognition of OSE is a critical part of this. Moreover, we are pursuing strategies that focus on the therapeutic induction of natural IgM.

More recently we discovered that complement factor H (CFH) specifically binds and neutralizes one type of OSE, namely malondialdehyde modifications. CFH is a major inhibitor of complement activation and genetic variants of it have been associated with a number of disease conditions. We are currently investigating if and how this newly found property of CFH plays a role in atherosclerosis and other inflammatory diseases. 


Christoph Binder was born in 1973 in Vienna, Austria. Following his studies of medicine at the Medical Faculty of the University of Vienna, where he obtained his MD degree in 1997, he entered a PhD program at the University of California in San Diego, where he obtained  his PhD degree in 2002. In 2005, he joined the Department of Laboratory Medicine at the Medical University of Vienna, where in 2009 he was appointed Professor of Atherosclerosis Research. In 2006, he joined CeMM as Principal Investigator. He is a specialist in laboratory medicine and leads a research group focusing on the role of immune functions in atherosclerosis and how these can be exploited for therapeutic interventions. He first described the atheroprotective effect of pneumococcal vaccination and the natural IgM T15/E06 (Binder et al., 2003). His research group discovered that certain oxidation-specific epitopes derived from lipid peroxidation are major targets of natural antibodies (Chou et al., 2009) and of complement factor H (Weismann et al., 2011). He also identified the protective roles and mechanisms of the cytokines IL-5 (Binder et al., 2004) and IL-13 (Cardilo-Reis et al., 2012), as well as natural IgM antibodies (Gruber et al., 2016; Tsiantoulas et al., 2017; Obermayer et al., 2020) in atherothrombosis. His recent work has also focused on the  identification  and  characterization  of  mitochondrial extracellular vesicles (Puhm et al., 2019). He has won numerous prestigious fellowships and awards and has authored > 130 publications in renowned journals, including NatureMedicinand Nature.
